Most are harmless.
Two are not.
Hundreds of spider species live in Missouri, and most can’t even break your skin. They bite only in self-defense, not because they’re hunting you. Still, nobody wants them in the house. Here are the ones St. Louis homeowners find most often.
House Spiders
The webs in ceiling corners, window frames, and basements. Harmless to people, but a steady sign there are enough insects in the house to keep them fed.
Cellar Spiders
Long-legged and fragile, they build loose webs in damp basements and crawl spaces. Where you find cellar spiders, you’ll usually find a moisture problem worth fixing too.
Wolf Spiders
Big, fast, and alarming to find in the tub, but not dangerous. They hunt on the ground instead of building webs and usually wander in under doors and through foundation gaps.
The two to take seriously.
Missouri has exactly two venomous spiders: the black widow and the brown recluse. Bites are rare and very rarely serious when treated, but both are worth a call to your doctor and a call to us.
Black Widow
Shiny black, about a half inch long, and the female carries the telltale red hourglass on her abdomen. Widows prefer undisturbed outdoor spots: woodpiles, shed corners, the dark side of the garage. Finding one indoors is rare. They’re nocturnal and stay in the web during the day.
If you’re bitten, seek medical attention. Then let us find the nest instead of reaching into it yourself.
Brown Recluse
Light brown with a violin-shaped marking behind the head, and six eyes instead of the usual eight. Easily confused with harmless species, and unlike the widow, the recluse is common inside St. Louis homes: closets, boxes, attics, anywhere quiet. Bites are uncommon but should be seen by a doctor.
Seeing them regularly? Recluse control takes a targeted, whole-house approach. Call us at (314) 720-8857.
We treat where they live, not just where you see them.
Knocking down a web fixes the corner, not the problem. Spiders follow food, moisture, and shelter, so effective control addresses all three. Here’s what a visit looks like.
Free On-Site Inspection
A licensed Titan tech identifies the species you’re dealing with and finds the cracks, voids, entry points, and moisture conditions drawing them in. You get a written quote before any work starts.
Same day or next dayTargeted Treatment
We remove webs and egg sacs, then treat the cracks, voids, and entry points where spiders actually harbor. Products are applied per label directions, only where they’re needed.
One visitPrevention
Spiders stay where the food is, so we also address the insects they eat, plus the moisture and clutter that shelter them. An optional recurring plan keeps populations down through St. Louis seasons.
Ongoing protectionWhat people ask about spiders.
Are the spiders in my house dangerous?
Most aren’t. The vast majority of spiders in Missouri can’t bite through human skin and only try in self-defense. The two exceptions are the black widow and the brown recluse. If you’re not sure what you’re seeing, save a photo (or the spider itself in a jar) and we’ll identify it during your free on-site inspection.
Will one treatment get rid of spiders for good?
A single visit knocks down the population you have now: webs and egg sacs removed, harborage areas treated. Long-term control comes from prevention, because new spiders move in wherever food, moisture, and shelter are available. Many homeowners pair the initial treatment with a recurring plan so populations stay down through the year.
Why do I keep seeing spiders even though my house is clean?
Spiders don’t care how clean the house is, they care whether there’s food. If spiders keep showing up, there’s an insect population feeding them, often plus extra moisture in a basement or crawl space. That’s why our approach treats the insects and conditions along with the spiders themselves.
Is spider control included in a service plan?
Yes. Spiders are covered under our Home Shield plan along with ants, roaches, mice, and the other common household pests, with free callbacks between visits if a covered pest returns.
Seen one too many?
